Table 1. Recent publications of systematic review and meta-analysis regarding supramaximal resection in GBMs.

Class	Year	Number of enrolled studies	Number of patients	Conclusion
Incekara et al. [31]	2019	6	1,168	Compared with GTR, SMR of GBM resulted in a lower risk of mortality and longer median OS.
Dimou et al. [12]	2020	7	2,019	Preliminary results are promising but has low quality.
Jackson et al. [32]	2020	11	2,056	SMR may be associated with improved OS compared to GTR.
Wach et al. [17]	2023	11	1,168	The median PFS was longer in SMR group than GTR group. The rate of complications was comparable between the two groups.

GTR, gross total resection; SMR, supramaximal resection; GBM, glioblastoma; OS, overall survival; PFS, progression-free survival
